Large Aperture Multi-Object Fiber Spectroscopic Telescope (LAMOST; also called Guo Shoujing telescope), is a quasi-meridian reflecting Schmidt telescope with the effective aperture of about 4 meter. In its 5-degree field of view, 4000 fibers are installed, which is capable of obtaining the same number of low resolution spectra (R~1800) covering from 380 to 900 nm simultaneously. The on-going LAMOST spectroscopic survey is focusing on both the stars and some bright extragalactic objects. In its 5-year survey plan, it will obtain a few millions of stellar spectra in about 20,000 square degrees in the northern hemisphere. LAMOST has delivered its fifth data release (DR5), containing about more than 8 million stellar spectra. It provides stellar effective temperature, surface gravity, [Fe/H], and line-of-sight velocity, with precision of about 110 K, 0.2 dex, 0.15 dex, and 5 km/s.

These observations provide us vital important opportunities to study our Milky Way in multi-viewpoints. This conference will focus on the following key topics:

1. Introduction to LAMOST and other leading surveys: LAMOST, Gaia, etc.; Cross-calibrating spectroscopic surveys

2. Stellar physics: peculiar and metal-poor stars, asteroseismology, variables/ binary stars, massive and low-mass stars

3. The bulge/bar: shape, kinematics, and chemistry, theories

4. The Galactic disk: kinematics and dynamics, chemo-dynamical evolution, spiral arms

5. The Galactic halo: structure of the stellar halo, dark matter halo

6. Interstellar and circumstellar materials: gas, dust, extinction, molecular cloud

7. Future photometric/spectroscopic surveys
